Recently, home network system is providing more various services as home robot applied. A home robot not only basically controls home device but also services prevention of crimes, prevention of disasters through home monitoring and various entertainments while it navigates the autonomously based home network system. However, for the existing home robot to it is not easy to install all functions because the size of robot device becomes larger and the management of contents and applications executed becomes uneasy and has difficulties in adding new functions. Moreover many improvements are necessary for functioning of robot's location awareness. In this paper, we propose a more improved home robot system which uses resources of the robot efficiently as it divides the complicated operation of the robot among external digital device and adds new functions easily and recognizes the location of the robot by RFID.

In this paper, a service mobility scheme using user's location & service information table management and user recognition skill is proposed to support the movement of the multimedia service user and provide the seamless multimedia service environment in home network. We analyzed the proposed scheme using queueing system and we built test bed for experiment onthe proposed scheme to verify the operation and performance. As a result, we can show the proposed scheme provides a seamless multimedia service through the new client terminal when a user move to the new location and shows the performance completing the service mobility through the new client terminal within the service delay time which is shorter than the service delay time generated in the previous scheme.

The purpose of this study is to identify the effects of interactivity, computer playfulness, and computer anxiety on service satisfaction, attitude, and user intention based on the flow theory in order to understand factors improving effects of home-network system. Especially, Computer anxiety which is one of individual characteristics in negative aspect as well as computer playfulness was added to the research model to perform empirical research for grasping effects on attitude variables such as service satisfaction. The analysis resulted that the perceived interactivity and the computer playfulness had a positive relationship with service satisfaction, but on the contrary it was identified that the computer anxiety gave a negative effect on the service satisfaction. These results are evidences to explain high correlation of the perceived interactivity, the computer playfulness, and the computer anxiety with the service satisfaction. Besides, it was found that there was a meaningful relationship among the three attitude variables such as satisfaction, attitude, and intention to use. This research suggested an integrative research model using home-network technology where user satisfaction and use factors were included, expanded research area of the traditional interactivity, and presented a consistent result to support the relationship among the service satisfaction, the attitude, and the intention to use. In additions, practical issues were also provided by presenting user's criteria for selecting various services including electronic commerce and its using elements continuously.

It is rapidly expanding to provide Home Digital Service based on the Home Network System in intelligent apartment. Fortunately, Korea has one of the highest rates of Internet penetration and access in the world. Construction companies used the Home Network system as a strategy of differentiation and it is available to the customers to raise their asset value. Besides, the government has a positive response to accept the new movements to make the digital environment with 'u-Korea (Ubiquitous Korea)' as the slogan. However, the level of providing Home Digital Service is actually at the beginning. The develop the home network industry more effectively, the related industries' cooperation is essential. The purpose of this study is to propose a providing model of Home Network System for the construction company and to make a method to response the fast change of technology development and customer's request at the point of construction companies' view.

The research is on progressing to operate digital door lock with the method to guarantee the security and safety in the meantime to use digital door lock conveniently using Internet of Things (IoT) standardizing various service providing technology using IoT in home network currently. In this study, compose home network interconnecting Raspberry-PI and web server reflection this trend and composed the system to control the door lock after connect Arduino substituting converter function. Making Raspberry-PI using dynamic IP address using existing open source easily maintain DNS information and possible to connect internet network in home network ethernet and finally, making the smartphone can control door lock remotely entering designated address after connect the internet. The connection between home network and Arduino is executed by Raspberry-PI and bluetooth pairing as 1:1 and make random user's access to be impossible. Especially, to make open/close the door lock with smartphone not by using password on the keypad or using RFID card is judged as the method increasing the security make random user's access to be impossible and also increased the usefulness making remote control to be possible.

User needs in residential environment have very complicated and variety connection with others. u-home system for the near future is need to be combined acceptance of exist user needs as well as needs on new technology relating with u-Home. The study proposes a User Behavior Analysis Framework - UBAF for applying the user needs to the system more efficiently and developing the system by classifying patterns for the needs based on date of user behavior analysis. UBAF is a developing framework getting the basic idea of combining system modeling methods on SE and user modeling methods considering on HCI. It will be applicable to develop the system with core user behaviors by applying a standard way on u-Home. For example, the study transforms information into knowledge the system modeling and user modeling with analyzing a scenario for indoor temperature controlling on u-Home.
